Frontal bristles as a rule less descending on cheeks than in 

 Eutachininae, sometimes only to insertion of antennæ, generally 

 all Crossing, but often with an upper outwards directed bristle in 

 female or in both sexes. Often less than three præsutural acrostichals. 

 Most often only one posthumeral bristle, and nearly always no præ- 

 sutural intraalar bristle. Sometimes only three scutellar marginal 

 bristles on each side, and often the apical somewhat large:
